* PersistentVolumeLabel admission plugin, responsible for labeling `PersistentVolumes` with topology labels, now does not overwrite existing labels on PVs that were dynamically provisioned. It trusts the  dynamic provisioning that it provided the correct labels to the `PersistentVolume`, saving one potentially expensive cloud API call. `PersistentVolumes` created manually by users are labelled by the admission plugin in the same way as before. ([#82830](http...

Over the last year, SIG Storage has been focused on adding support for the Container Storage Interface (CSI) to Kubernetes. The specification recently moved to 1.0, and on the heels of this achievement, Kubernetes v1.13 moves CSI support for PersistentVolumes to GA.

With CSI the Kubernetes volume layer becomes truly extensible, allowing third party storage developers to write drivers making their storage systems available in Kubernetes without having to touch the core code.

### Experimental Features

  * Dynamic Provisioning of PersistentVolumes: Kubernetes previously required all
volumes to be manually provisioned by a cluster administrator before use. With
this feature, volume plugins that support it (GCE PD, AWS EBS, and Cinder) can
automatically provision a PersistentVolume to bind to an unfulfilled
PersistentVolumeClaim.

* Alpha annotation for PersistentVolume node affinity has been removed.  Update your PersistentVolumes to use the beta PersistentVolume.nodeAffinity field before upgrading to this release. ([#61816](https://github.com/kubernetes/kubernetes/pull/61816), [@wackxu

* Disable linux/ppc64le compilation by default ([#30659](https://github.com/kubernetes/kubernetes/pull/30659), [@ixdy](https://github.com/ixdy))
* Implement dynamic provisioning (beta) of PersistentVolumes via StorageClass ([#29006](https://github.com/kubernetes/kubernetes/pull/29006), [@jsafrane](https://github.com/jsafrane))

- Adds the `ReadWriteOncePod` access mode for `PersistentVolumes` and `PersistentVolumeClaims`. Restricts volume access to a single pod on a single node. ([#102028](https://github.com/kubernetes/kubernetes/pull/102028), [@chrishenzie](https://github.com/chrishenzie))

### Bug or Regression

- Fixed PersistentolumeLabel providing wrong topology labels to Azure Disk PersistentVolumes when the external Azure cloud provider is used. ([#124528](https://github.com/kubernetes/kubernetes/pull/124528), [@jsafrane](https://github.com/jsafrane)) [SIG Cloud Provider]

tes/enhancements/issues/361) makes it possible to set requests and limits on ephemeral local storage resources. In addition, you can now create [Local Persistent Storage](https://github.com/kubernetes/enhancements/issues/121), which enables PersistentVolumes to be created with locally attached disks, and not just network volumes.

On the Persistent Volumes side, this release [Prevents deletion of Persistent Volume Claims that are used by a pod](https://github.com/kubernetes/enhancements/issues/498)...

    *   Added file system resizing for the following volume plugins: GCE PD, Ceph RBD, AWS EBS, OpenStack Cinder
*   [alpha] Topology Aware Volume Scheduling
    *   Improved volume scheduling for Local PersistentVolumes, by allowing the scheduler to make PersistentVolume binding decisions while respecting the Pod's scheduling requirements.
    *   Dynamic provisioning is not supported with this feature yet.
*   [alpha] Containerized mount utilities
